Dept of Pharmacology, University of Cambridge
UK Proteostasis Network Coordinator
Co-Coordinating Committee Member
My research interests include protein folding, engineering and design; molecular therapeutics; and targeted protein degradation. My group is exploiting our understanding of protein-protein interactions to harness proteostasis networks and thereby manipulate protein stability and disease outcome. We are combining target-engagement modules and degradation-inducing modules in a mix-and-match format to identify the best combination for effective knockdown of the target with the aim of co-opting the broadest range of degradation machineries and thereby tackling hard-to-drug targets and disease states.

We are interested in the protective role of proteostasis mechanisms in neurodegenerative diseases. In particular, our lab investigates how chaperones and autophagy work in glial cells, mainly in astrocytes, and their relevance to glial function and glia-neuron communication.

Keywords: Neurodegeneration; Protein folding and chaperones; Protein degradation

My scientific interests lie in the area of intracellular protein trafficking and degradation pathways. The current focus of research in my laboratory is molecular mechanisms and cellular functions of autophagy.

Keywords: Neurodegeneration; Lysosome; Ageing

We study autophagy in various mammalian cell models, from tissue culture immortalised cells to iPSC-derived neurons.

My lab studies autophagy and its roles in promoting cellular resilience. We mainly use human induced pluripotent stem cell (hiPSC)-derived neurons and glia to test how autophagy contributes to neuronal resilience and neuroinflammation in Parkinson's and other human neurodegenerative diseases.

Keywords: Stress responses; Neurodegeneration; Mammalian models / cell culture

Patrick Lewis

Department of Comparative Biomedical Sciences, Royal Veterinary College, University of London
My group investigates how genetic variants can influence the risk of developing neurodegenerative diseases such as Parkinson's, with a particular focus on mutations in LRRK2. There is strong evidence linking LRRK2 to Proteostasis via macroautophagy and lysosomal dysfunction.

Keywords: Neurodegeneration; Lysosome; Aggregation

Susana R. Louros

Centre for Discovery Brain Sciences, Simons Initiative for the Developing Brain, University of Edinburgh
My lab is investigating how dysfunctional protein turnover results in synaptic dysfunction, circuit abnormalities and behavioral changes in models of autism and intellectual disability. Our aim is to understand how best to leverage the UPS pathway for therapeutic benefit of neurodevelopmental disorders.

Girish Ram Mali

We investigate how cells assemble large multi-subunit motor proteins called axonemal dyneins which power the rhythmic beating motion of eukaryotic cilia and flagella. Our major focus is a newly discovered family of structurally and functionally diverse proteins called Dynein Axonemal Assembly Factors/DNAAFs which shepherd the folding and assembly of individual dynein subunits into functional macromolecular motors. To uncover the molecular mechanisms of DNAAFs, we combine biochemistry, integrative structural modeling, cell biology, and proteomic approaches.

Glenn Masson

School of Medicine, University of Dundee
Our research group is interested in GCN2, and how this is activated in cancer cells under proteostasic stress. We are looking to develop drugs which can be used to select cancer cells which have altered amino acid metabolism to compensate for the low nutrient conditions of the tumour microenvironment. We use a variety of tools to do this, primarily structural biology, biochemical and biophysical analysis, and well as cell and tissue research.

Liz Miller

Molecular, Cell and Developmental Biology, University of Dundee
Co-Coordinating Committee Member
Research in the Miller lab is broadly aimed at understanding basic mechanisms of secretory protein biogenesis, focusing on protein quality control and export from the ER. Our current focus is on the mechanisms of COPII vesicle formation and cargo selection.

Keywords: Protein transport; Protein translation and ribosomes; Protein folding and chaperones

Healthy Ageing & Chronic Conditions Research Institute, Medical School, Swansea University
Co-Coordinating Committee Member
My laboratory is using a new teleost model to understand vertebrate ageing mechanisms. We focus on the loss of proteostasis at the organismal level and how this affects healthspan and longevity.

Yvonne Nyathi

School of Biomedical Sciences, Faculty of Biological Sciences, University of Leeds
Our laboratory investigates molecular mechanisms of membrane protein proteostasis, from their synthesis to integration into target membranes. Employing a multidisciplinary approach, we harness proteomics, high-resolution imaging, bioinformatics, biochemistry, and structural biology to deepen our understanding of these vital processes and their impact on cellular function and disease.

We are interested in understanding how toxic protein aggregates and proteotoxic stress affect cellular fitness and cell competition. We use Drosophila and several in vitro models including human ES cells and their derivatives for our studies.
